Let the 10-week madness in the Sprint Cup Series begin. Sunday's 400 mile race at Chicagoland Speedway kicks off the 2012 Chase for the Sprint Cup championship. It's the second straight year Chicagoland hosts the opening round in the playoffs. New Hampshire started the Chase each year from 2004 to 2010. Just 12 points separate top-seed Denny Hamlin from 12th-place Jeff Gordon. Our live coverage of the GEICO 400 on AM 1590 and FM 95.5 starts at one o’clock Sunday afternoon.
